Why is not possible to draw a circle with a circumference of 100cm?
It is possible. Just keep the drawing instrument 15.915 cm from a set point (the circle's center).
Is it possible to draw a circle of negative radius?
Radii are always positive. No, it is not possible to draw a circle with negative radius.
How do you find a chord of a circle with diameter 26?
There are an infinite number of possible chords in anycircle, regardless of its diameter. A chord is a line segment with its endpoints on the curve (circumference) of the circle. You can draw those all day and never draw the same one twice.
Divide a circle into 12 equal parts?
Use a pair of compasses to draw a circle. Without changing the compasses, place the point of the compasses on the circumference and draw a small arc such that it intersects the circumference. Put the point on this intersection and repeat until you have 6 equally spaced "intersections". Select 2 adjacent intersections and, from each of them, draw an arc outside the circumference such that the 2 arcs intersect. Draw a line from this intersection to the centre of the circle. This line intersects the circumference halfway between the adjacent points. With the compasses set to the original radius of the circle (it's better to leave them fixed at this throughout!) place the compasses' point on the intersection of the straight line and the circumference then draw a series of arcs, as you did originally. These will complete the division by 12
What is an arc in math?
An arc is a portion of the circumference of a circle, and the circumference of a circle is the distance round a circle. So an arc looks like a semicircle, it is part of the circumference. Arcs are often used in constructions, for example if you were asked to draw an angle of 60 degrees without a protractor you would draw arcs following a special method. Arcs are drawn using a tool called a pair of compasses.
Is it possible to draw a circle whose ratio of circumference to diameter is not pi?
No, the circumference divided by the radius will always be pi for a circle.
Why is not possible to draw a circle with a circumference of 100cm?
It is possible. Just keep the drawing instrument 15.915 cm from a set point (the circle's center).
Is it possible to draw a circle with a circumference of thirty inches inside a square of 100 inches when 3 equals pi?
Yes
How do you draw an inscribed rectangle?
Draw two diameters of the circle and join the points where they meet the circumference.
Is it possible to draw a circle of negative radius?
Radii are always positive. No, it is not possible to draw a circle with negative radius.

What Are The steps used in the construction of an equilateral triangle inscribed in a circle?
Draw a circle using a compass. Then, without changing the compass setting, place its point on the circumference of the circle, at any point A, and draw two arcs to intersect the circumference at B and C. Move the compass to B and draw another arc to intersect the circumference at D; and then from C to E. ADE will be an inscribed equilateral triangle.
How do you get a radius?
# Find the center of the circle # Draw the line of the radius from the center to the circumference # Finish
How do you draw a diagram that shows what pi means?
-- Draw a circle. -- Put a mark at the center, and draw a line across the whole circle through the center. -- Measure the length of the curved line all around the circle. (called the "circumference" of the circle) -- Measure the length of the straight line across the circle. (called the "diameter" of the circle) If you divide the circumference by the diameter, the result is 'pi'. It doesn't matter how big or how small the circle is. The result is always the same.
How do you discover pi?
First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.

Is it possible to draw a circle with a circumference of 30 inches inside a square with the area of 100 inches?
Yes because each side of the square is 10 inches and 30/pi gives the circle's diameter as 9.549296586 or about 9.5 inches
